JHS’ nod to the ProCo RAT!

The PackRat is the ultimate tribute to the 40+ years of rodent evolution and its impact on the guitar’s sound.

Artists from every genre have used the Rat’s iconic tones to create their sounds, including Nirvana, Pink Floyd, Metallica, REM and Radiohead.

Building on the success of the Muffuletta and Bonsai, the PackRat uses the same unique system to direct the paths of 261 components through 40 switches.

This means that, when you choose one of the 9 legendary or rare modes, you are playing fully analog circuits that perfectly replicate that mode.

If you purchased these nine hard-to-find pedals on the used market right now, you would pay around $4,000!

Let’s take a look at the controls.

The operation of the PackRat is about as simple as it gets.

The “Volume” control adjusts the overall volume of the pedal.

The “Distortion” control lets you raise and lower the amount of gain that the circuit produces.

The “Filter” control allows you to brighten and darken the sound of the overall effect. This is effectively a simple, low-pass filter.

Lastly, the “Mode” control lets you scroll through the 9 legendary versions of this circuit.

As you change the mode, the analog circuitry is rewired, resulting in brand new values of resistors, capacitors, diodes and op amps!

The PackRat Modes:

1 - The OG : A perfect recreation of the first production RATs ever made.

2 - White Face V3 : This mode will switch to a tapered “Filter” control with an entirely different feel.

3 - Turbo V6 : A more touch sensitive version of the RAT circuit.

4 - BRAT : A recreation of the 1997 ProCo BRAT.

5 - Dirty : This one gives the most saturation and waveform clip-off of any version ever made.

6 - LA : An “LA Metal”-style distortion. One of the best-modified RAT circuits of the 1980s!

7 - Landgraff MO’D : Pays homage to the John Landgraff MO’D, a distant cousin of the RAT.

8 - Caroline : Inspired by the Caroline Guitar Co Wave Cannon, a clever take on the RAT circuit.

9 - JHS : The JHS PackRat mod, as performed on thousand of RAT pedals from 2008-2018.
